Americans on Sunday marked the 21st anniversary of the 9/11 attacks, with President Joe Biden visiting the Pentagon and New Yorkers honouring the nearly 3,000 people killed when hijacked planes destroyed the Twin Towers.
Relatives of victims, police officers, firefighters and city leaders gathered at the National September 11 Memorial in Lower Manhattan, where the names of those who died were read aloud – as they have been every year since the deadliest single attack on US soil.
They rang bells and held moments of silence at 8:46 am and 9:03 am (1246 and 1303 GMT), the precise times the passenger jets struck the World Trade Centre’s North and South Towers.
Biden commemorated the anniversary at the Pentagon, where Al-Qaeda hijackers crashed a plane into the massive building that serves as Defence Department headquarters.
In a steady rain, the president approached a wreath of flowers outside the building and placed his hand over his heart.
“Twenty-one years later, we keep alive the memory of all the precious lives stolen from us at Ground Zero, in Shanksville, Pennsylvania, and at the Pentagon,” Biden said on Twitter ahead of delivering remarks.
“To the families and loved ones who still feel the ache, Jill and I hold you close in our hearts.”
Al-Qaeda hijacked a total of four planes. The third hit the Pentagon and the fourth, Flight 93, crashed in a field in Pennsylvania after passengers launched a revolt onboard.
Vice President Kamala Harris, Homeland Security Secretary Alejandro Mayorkas and Mayor Eric Adams were among the dignitaries attending the New York ceremony, where relatives hugged one another, placed flowers at the memorial and held placards or wore shirts with images of their lost loved ones.
“While the grief recedes a bit with time, the permanent absence of my father is just as palpable as it ever was,” the son of Jon Leslie Albert said after reading several victims’ names, including his father’s.
Messages of sympathy and support came from outside the country, including from NATO Secretary General Jens Stoltenberg and Ukrainian President Volodymyr Zelensky, who called September 11 “one of the most tragic days” for the US and the world.
New York was illuminated late Saturday by a “Tribute in Light” that showed two blue beams projecting into the night sky symbolizing the Twin Towers.
